To LZZ whom, it may concern.-

Beit known that I, CARL JNGST, asuhj eet of the King` of Prussia, residing at Freienwalde, on the Oder, in the Kingdom of Prussia, Germany, have invented new and useful Improvements in Rooingdiles, of which the following is a specication.

My invention relates to the manufacture of ribbed or gooved roolingtiles produced by continuous tilemaking machines in which the clay is pressed in a conti nuous column through a die having the required coniiguratiomand is cut into lengths. The forms of such tiles at present in use, adapted for overlapping each other, with ribs and grooves, are subject to several disadvantages both in respect of their manufacture and in the use thereof for rQof ing. The configuration or profile of such tiles has generally been such that the tiles cut from the column of clay extended through the die of the machine received insuflicient support on the table, and consequently got deformed; also, at the upper side of the top end a por tion of the ribs or projections were cut away or pressed out, or the tiles were atA some parts disproportionately thin, preventinga close fit when placed in position for roofing. Furthermore, the tile frequently became cracked in burning at the weakened parts, thus impairing their durability, and, owing to the configuration of the tiles, the extent to which they could overlap was limited, as the top end of the tile would only lit properly together with the covering-tile when in a definite position.

Consequently a definite distance of the snpporting-battens is required, which in many cases is inconvenient. Bytheimproved manufacture of tiles, now to be described, these in conveniences and defects are obviated, and the production of the tiles by means of suitable machines is easy and certain.

The improved forln of tile is shown in plan and section at Figures l and 2 of the accompanying drawings. As shown at Fig. 2, the tile consists of two symmetrical halves, and is formed of a slab, or, of uniform thickness throughout. On the upper and under sides the tile has parallel ribs, which are also symmetrical on both halves. Figs. 5 and 6 show, in elevation and plan, the month-piece or die of the machine. The clay column extruded from this has on its under side a continuous rib, a, Fig. 5, which is cut off by means of a wire in the known manner, leaving a short length for forming the stud for hanging the tile on the support. (See dotted lines, Fig. l.) Fig. 3 shows the arrangement of the tiles when fitted together in roofing.

The ribs on the under side of the tile A t accurately into the grooves ofthe two contiguous lower tiles, so as to produce a perfect closure. As will be readily seen from Fig. 3, the builder is not limited to a definite distance apart of the battens p, as the tiles A and B can overlap each other to any desired extent, for

all the grooves extend throughout the length of each tile, and this is a characteristic feature of my invention.

As shown at Fig. 4, the holding-studs of the tiles are replaced by holes, enabling the tiles to be fixed to the battens by nails. Vith this arrangement the tiles may be used with either side uppermost, thus affording an advantage that has hitherto not been attainable.

It willbe evident that the tiles may also be provided with two studs instead of only one, as shown in dotted lines in Fig. 2.

I claim as my invention l. A rooiingtile consisting of a slab of uniform thickness throughout with parallel ribs and grooves, all the latter extending throughout the length of the tile and arranged symmetrically, substantially as described,wherehy when in use the ribs of an upper tile lit the grooves of a lower tile with any extent of overlap, substantially as set forth.

2. A roofing-tile consisting of a slab of uuiform thickness having a hole for a securingnail, and having parallel longitudinal ribs and grooves arranged symmetrically, the grooves extending throughout the length of the tile, substantially as described, whereby when in usean upper tile iits closely with its ribs in the grooves of the lower tile with any extent of overlap, substantially as described.

In testimony whereof I have signed my name to this speciiication in the presence of .two subscribing witnesses.
